  Q: How to remove the Harmonic Balancer on 1997 through 2001 Toyota Solara?

  A: Remove the oil pan, pick-up tube, and oil pump. Loosen the harmonic balancer mounting bolts in the recommended sequence, 1/4 turn at a time, until you can unscrew them by hand. Remove the harmonic balancer. Secure the spacers with the harmonic balancer assembly by using wire or twist-ties. Before installing it, make sure to check the harmonic balancer for excessive backlash.

  Q: How to measure backlash in the engine balancer assembly on 1997 through 2001 Toyota Solara?

  A: The harmonic balancer assembly consists of two shafts contained in an upper and lower aluminum housing assembly. The shafts are geared together, and one of the shafts is geared to the crankshaft. The following procedure applies only when the harmonic balancer assembly is removed from the engine. Do NOT disassemble the harmonic balancer assembly! Start with the punch marks on the number 2 shaft lined up as indicated. The balancer shafts have punch marks and the number 2 housing has alignment notches - start with the shafts aligned, then align the number 2 shaft so that mark D is aligned with the housing. Using locking pliers to hold the number 2 shaft from turning, measure the backlash on the number 1 gear with a dial indicator. Set up the dial Indicator as shown and measure the backlash while applying mild hand pressure on the rear of both shafts, while keeping forward pressure on the rear of both shafts to eliminate thrust play. Compare the backlash to the specifications. Remove the dial indicator and turn the number 2 shaft so that punch mark E now aligns with the case. Measure backlash again compare the results with the specifications. Remove the dial indicator again and turn the number 2 shaft so that punch mark F now aligns with the case. Measure backlash again compare the results with the specifications. If any of the three measurements exceed the specifications, it is suggested that the harmonic balancer assembly be taken to a Toyota dealer or other qualified service facility for further disassembly and repair.

  Q: How to install Harmonic Balancer on 1997 through 2001 Toyota Solara?

  A: After installing, torquing, and checking the crankshaft and Pistons/rods, clean the surface of the block and the Harmonic Balancer spacers. Then, place the spacers on the block. Turn the crankshaft until the number 1 piston is at TDC. Align the punch marks on the balance shafts with their corresponding marks on the housing. Place the Harmonic Balancer on the block and install the bolts. Apply hand pressure on the center of the assembly in the indicated direction and tighten the bolts in several steps, following the sequence shown. Position a dial indicator against the end of the number 1 balance shaft and check the shaft endplay while pushing the shaft back and forth by hand. Repeat the check for the number 2 balance shaft and compare your readings to the specifications. If the endplay is excessive, remove the Harmonic Balancer and take it to a dealer service department or other qualified service facility for repair. Check the balancer shaft gear-to-crankshaft gear backlash at the four indicated locations. Rotate the crankshaft several revolutions and return to TDC for the number 1 piston. Check that the punch marks are still aligned. Rotate the engine clockwise until punch mark A lines up with the notch in the balancer housing. Position a lever-type dial indicator on the side of a tooth of the number 1 shaft gear. Lightly twist the number 1 shaft back and forth a few times by hand and, while pressing on the rear of the shaft to take up the endplay, lightly twist the shaft while observing the dial indicator. Compare the results to on-engine balancer backlash. Remove the dial indicator and rotate the engine clockwise until punch mark B on balance shaft 1 lines up with the notch in the housing. Measure backlash at this position and compare the results to on-engine balancer backlash. Repeat the previous steps and compare the results to on-engine balancer backlash. If any of the readings exceed specifications, change the spacer between the block and the balance assembly to obtain proper backlash. To increase backlash, select a thick spacer; select a thinner spacer to reduce backlash. Changing the spacer by 0.0008-inch changes the backlash by 0.0006-inch. Note: Various size spacers are available at your Toyota Dealership.
